To create a new Master theme:
Copy
Copy your Master starter theme within the EasySiteWeb folder on your pc or development server. Example file path:
C:\Development\Data\EasySite_v6_0\Application\EasySiteWeb\EasySite\StyleData\
Rename
Give the Style an appropriate and easily identifiable name, for example, ER_Master (the client or site’s initials in caps, then an underscore, then the style type.
For style variants you might use HP for homepage or LG for low graphics).
Find and replace
Find and replace all references to the previous style name, for example:
/EasySiteWeb/EasySite/StyleData/Training_Master/Images/background.png
changes to:
/EasySiteWeb/EasySite/StyleData/ER_Master/Images/ background.png
This file path will be used in various css files when referencing background images. It may also be used in ascx file to reference script files.
Import
Import the style into Easysite, making sure to set the relevant inheritance properties.
Create
Create a new page in Easysite and apply the style.
Change
Make changes to the css, code files and page controls as appropriate in order to achieve your design.
Test & validate
View the changes in your browser. Make sure to test your styles across a variety of browsers and operating systems. You may also want to test mobile devices.
Check that the html and css validate.
To create a new Variant theme:
Remember, for a variant theme you only need to include those files which are different to the Master theme. For instance this might be /PageControls/DocumentMasthead.ascx. Or it might be just /CSS/Variant.css.
If copying page controls, then you will probably want to begin by copying your Master style and deleting those things you don't need.
If all you need is a CSS file then there is no need to copy anything. Just create a new folder (for instance, ER_HP), a sub folder and a file: /CCS/variant.css
